Before RNA copies of genes can program the synthesis of proteins, the non-coding regions are removed by the spliceosome. Munich researchers report that distinct conformations of a member of this molecular complex play a vital ...

They found that RNA-binding proteins are regulated such that gateway proteins can recognize and block aberrant strands of genetic code from exiting the nucleus. Unused messenger RNA (mRNA) strands that cannot exit the nucleus ...

Research conducted at the National Superconducting Cyclotron Laboratory at Michigan State University has shed new light on the structure of the nucleus, that tiny congregation of protons and neutrons found at the core of ...

A group coordinated by SISSA Trieste has built a 3-D computer model of the human genome. The shape of DNA (and its sequence) affects biological processes and is crucial for understanding its function. The study has provided ...

An LMU team has succeeded in correctly packaging the complete yeast genome using purified components in the test-tube. This is a first that yields new insights into the mechanisms of genome organization above the level of ...

Over the past two years, Rosetta has kept a close eye on many properties of Comet 67P/Churyumov-Gerasimenko, tracking how these changed along the comet's orbit. A very crucial aspect concerns how much water vapour a comet ...

In a new paper, University of California, Riverside theoretical physicist Flip Tanedo and his collaborators have made new progress towards unravelling a mystery in the beryllium nucleus that may be evidence for a fifth force ...

Cygnus A is an elliptical galaxy around 600 million light years from the Earth, which has a supermassive black hole at its centre. It is one of the brightest sources of radio waves in the sky and was featured in Contact, ...

This striking view of Comet 67P/Churyumov–Gerasimenko reveals portions of both comet lobes, with dramatic shadows on the 'neck' region between them. It was taken by Rosetta's navigation camera (NavCam) on 30 June 2016, ...
